    摘要: An electronic key telephone set in an electronic key telephone system which is connected to the office line during the power failure by a power failure detecting relay in the key service unit having a common selection signal sender is provided with a circuit for detecting power failure to the key telephone system, additional contacts to respective keys of the key dial and a selection signal generator coupled with the additional contacts. The selection signal generator is connected to the voice signal pair line by a transistor which is turned on by a signal from the power failure detecting circuit during the power failure, and receives a D.C. power on the office line to be operable, so that a call may be generated from the key telephone set even during the power failure to the key telephone system. The signal from the power failure detecting circuit is fed to the transistor through a photo-coupler element.

    摘要: An image forming apparatus includes an image bearing drum for carrying a toner image; an intermediary transfer member; a primary transfer device for primary transfer of a toner image from the drum onto the intermediary member; a secondary transfer device for secondary transfer of the toner image from the intermediary member onto a sheet; and a cleaning unit for removing the toner on the intermediary member. The cleaning unit includes a scraping member for removing the toner deposited on the intermediary member, an accommodating portion for the removed toner, a discharging member, provided downstream of the scraping member with respect to a moving direction of the intermediary member, for moving the toner in the accommodating portion to the intermediary member by application of a voltage, and a regulating member contacted to the discharging member to regulate an amount of the toner deposited on the discharging member.

    摘要: A circuit for converting a video signal into binary signals comprising a line image sensor for performing photoelectric conversion of an object to be read thereby producing pixel signals. Means are also provided for setting reference levels for respective sections of the line image sensor, the sections being divisions of the entire length of the line image sensor. A comparator compares each pixel signal with the reference level for the section to which the pixel signal in question belongs, to produce a binary signal. An interpolator is further provided for receiving the digital reference level data as is a D/A converter for converting the output of the interpolator to an analog reference level signal and supplying it to the comparator.
